After 4 winters and 57,000 winter km on my Chev Colorado I need new snow tires. But when I pressure-washed my steelies after removal it was clear they needed care and attention. I could have them sand-blasted and repainted, or even sand-blasted and powder coated. But my boat trailer has galvanized steelies. Any reason why I shouldn't sand-blast and galvanize my truck steelies?

Based on what it cost to galvanize my boat trailer, galvanizing looks like being cheaper than paint or powder coat and should be more durable. The Colorado has an uncommon 6 x 100mm bolt pattern so buying new aftermarket rims will be about double the quoted cost of sand-blasting/painting. Sand-blast/paint is $50CAD per rim; aftermarket steelies are $105CAD and the dealer wants $300CAD a piece for OEM! Galvanizing a 350lb trailer frame and ancillary bits cost me $270CAD, taxes in.The galvanizer charges by weight.

The only thought that comes to mind and it should not be an issue if the wheels are not heat treated is hydrogen embrittlement, but even if that were a concern a bake post galvanize should deal with it. Other than that as long as the finish is smooth enough to allow a good bead seal you should be good.
Curious to hear your decision/result.
